Hi,

I have a question in regards to CII (B31.3), if a straight piece of pipe is anchored at both ends ,the EXP load case does not bring into account the axial stress due to thermal expansion and the code stress would be zero and the pipe would not be shown as failed, however the axial stress could be more than the allowable stress.
I know this is not normally the case but should we always check the allowable stress against axial stress as well ?

Regards
